NT to Solaris 8 printing problem

I have a Sun Ultra 60 running Solaris 8, that has an HP LaserJet 6MP connected to it locally via the parallel port(/dev/ecpp0). The printer does not have an onboard NIC card/Etherenet jack. On the same subnet I have a Gateway E-4200 running Windows NT 4.0. The NT box won’t print to the printer. The Solaris machine prints with no problems. So, How do I get the NT machine to print to the printer on the Solaris box? I can’t add the printer via NT Add Printer wizard.I’ve looked everywhere, eg Microsoft, Sun, HP sites, etc., but to no avail. Any help would be greatly appreciated.
